Pavement performance depends on many factors. Mix designs, ambient and mix temperatures, rolling methods, joints, and types of equipment used can all be analyzed and tweaked to deliver a better ...

Of all the aspects of the hot mix asphalt paving process, compaction plays the most important role in determining the useful life of the finished pavement -- even more than the mix itself. Whether ...

We define amplitude, when referring to vibratory asphalt compactors, as the distance the drum moves into the mat. The weight of the drum, combined with drum movement, delivers impact force into the ...

Nationwide research is firming up the case for "intelligent" compaction, a construction method three decades in the making that could save billions of dollars a year in potholed roads, cracked bridges ...

An airfield pavement project at Philadelphia International Airport is using approximately 90,000 cu yd of foamed glass aggregate, which officials believe is the largest application of its kind in ...
